Del Toro is fantastic and I am a big fan but I haven’t seen any suggestions that he might have any interest in the cobbled classics.
In fact, Del Toro seems average to me on the flat sections.
As for the GT, we'll wait and see. In the two high-mountain stages of the Giro, he struggled quite a bit. Simon didn't just beat him in Finestre; remember, he also beat him in another stage. And Simon is a long way behind his leader, Vingegaard.
Carapaz didn't even make the Vuelta podium last year, against O'Connor and Mas.
Del Toro has a great future, but I've seen comments on X that see him as a Tour de France podium finisher next year, so be calm. I'm not sure he's a better climber than Lipowitz in the mountains.
The current Carapaz couldn't get on the podium with Mas and O'Connor. I don't think he's superior to the Lipowitz of the Tour, and Del Toro was at Carapaz's level at the Giro, and clearly inferior one day.
The races he's done since the Giro have been very poor. Although I think he's better in those types of races. I have more doubts about the GT mountain stages.
I don't see him overtaking Vingegard next year as some suggest. It's still early.
